High-flying winners of annual skyscraper competition

Honorable mention: Heritage Mirage: Digital Heritage Archive Skyscraper Based On Classification System, China. "“Heritage Mirage” digitizes heritage sites in the city and transforms the stored visual information into new building materials, stacking them up like bricks in the virtual world to create a tower of civilization, serving as an archive of the city’s collective memory." These are the high-flying winners of an annual skyscraper competition. The top designs - and runners up - in eVolo Magazine’s contest were selected from a total of 206 projects submitted. Established in 2006, the event "recognises visionary ideas that through the novel use of technology, materials, programs, aesthetics, and spatial organisations, challenge the way we understand vertical architecture and its relationship with the natural and built environments." The three winning projects, by designers from China and Egypt, propose solutions to bring agriculture into cities, ways to revitalise the Yellow River in China by restoring its bank, and a project that sees a kilometre-deep underwater skyscraper designed to filter the CO2 excess in the oceans.
